Control Valves, Accessories, and Parts

Control valves & replacement parts

The control valve runs the regeneration cycle on every softener and backwashing filter. We stock complete valves and the wear parts that keep them going across the three major brands — Fleck, Nelsen and Autotrol.

Find parts by brand

• Fleck — pistons, seal & spacer kits, brine valves, meters and SXT timers. See Fleck valves & parts.
• Nelsen WS1 — drive assemblies, pistons and o-ring kits.
• Autotrol — 255/460i & 460TC parts, timers and covers.

Most-replaced wear parts

Pistons, seals and spacers, brine valves and injectors are the usual culprits when a softener stops regenerating or runs to drain. Match parts to your exact valve model number for a clean fix.

FAQ

Nelsen vs Fleck — which is better? Both are excellent; Nelsen WS1 is prized for quiet, quick service while Fleck 5600SXT is the value standard with parts everywhere. Can I rebuild instead of replace? Usually yes — a seal/piston kit restores most valves for a fraction of a new head.
